System and Method for Analyzing Confidential Data

3. The method for analyzing confidential data of claim 2, in the step of inputting a third key into the cloud host to obtain an analysis output authorization, the cloud host further follows one of the plurality of second data to provide authorization to confirm the analysis output authorization, so as to continue to perform the step of the cloud host follows the analysis output authorization to output the second analysis result into the second analysis data.

6. The system for analyzing confidential data of claim 5, in which the end-user device further uploads a third key to the cloud host, the cloud host follows the third key to provide an analysis output authorization; the cloud host follows the analysis output authorization to output the second analysis result into a second analysis data.

7. The system for analyzing confidential data of claim 6, in which the cloud host further follows one of the plurality of second data to provide authorization to output the second analysis result into the second analysis data.

8. The system for analyzing confidential data of claim 5, in which the end-user device further uploads a third key to the cloud host; the cloud host follows one of the plurality of second data to provide authorization, and the third key provides an analysis output authorization; the cloud host follows the analysis output authorization to output the second analysis result into a second analysis data.

9. The system for analyzing confidential data of claim 5, in which the cloud host further connects to a data capturing device; the data capturing device captures a plurality of initial data in a big data database and sends them to the at least one encrypted storing unit; the cloud host de-identifies the plurality of initial data and generates the corresponded plurality of second data, stored in the at least one encrypted storing unit; the cloud host generates the plurality of first data by the cloud host simulating according to the format of the corresponded plurality of second data or randomly sampling the corresponded plurality of second data, and stores them in the at least one encrypted storing unit; the cloud host stores the second analysis result in the at least one encrypted storing unit.
